T 0 (ZZZ whom it may concern."

Be it known that I, CIrAnLns II. MELVIN, a citizen of the United States,residing at hLIoline, in the county of Rock Island and State ofIllinois, have invented certain new and useful lm n-m'emcnts inSulky-Ilows, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in sulky-plows, on which adjustablefront and rear fnrrmv-wheels are employed, and it refers moremrticularly to the means used to accomplish adjustment of thefurrowwheels.

My invention has for its object a more effective control of thefurrow-wheels, so that their position may be more readily varied atwill.

Referring to the drawings in which similar reference numerals indicateidentical parts-Figure 1 is a side view of a plow in perspective showingmy improvement. Fig. 2 is a plan view of Fig. 1, and Figs. 3 and 4 aredetails.

I have shown my improvement applied to a plow in which the frameconsists of a longitudinal frame'bar 1 supported by a front furrow-wheel2 and a rear furrowwheel 3, and a frame-bar 4t rigidly secured to theframe-bar 1, extending laterallylandward therefrom and semi-circular inshape, and on a suitable bracket thereon is journaled a landside-wheel5. A tongue 6 has a seat-support 7 mounted upon it, to which is attacheda seat 8.

The furrow-wheels 2 and 3 are journaled on axles forming the lower partof vertical spindles 9 and 10, which have their bearing in suitablebrackets secured to the ends of the frame-bar 1. Arms 11 and 12 arerigid with the spindles 9 and 10, and are connected by rods 13 and 1. 1with a sliding bracket 15 on the seat support 7, the inner ends of therods being bent to form hooks as shown, engaging with eyes 16 and 17 oneither side of the seat support and forming part of the bracket 15, apreferable and simple connection. The sliding bracket 15 embraces thesides of the seat-support 7 and is held thereon by a cross piece 18securely bolted to the bracket.

Projecting forwardly from a side of the bracket 15, and preferablyintegral therewith, is an arm 19 having an eye with which engages a bentend of a link 20, the forward end of the latter being also bent toconnect with the end of a lever 21 fulcrumed at the base of atoothed-segment 22 rigidly mounted on a brace 23 which is securelybolted to the seat support 7 at 24, and to a horizontal portion of theseat-support and the tongue (3 at 2.3. The lever 21. is provided withthe ordinary latching mechanism to engage with the teeth of the segment22, and being located close to the seat it is within easy reach of thedriver. As previously stated, the bracket 15 slides upon thescat-support 7, and, as shown in the drawing, is central of its totalmovement, the lever 21 being locked substantially central of the teethon the toothed segment 22, and the furrowwhcels 2 and 3 held se curelyparallel with the line of draft. It will be readily understood that bydisen. gaging the lever 21 from the toothed-segment 22 and moving itforwardly or backwardly, the bracket 15 is moved up or down on theseat-support 7, and the furrowwheels 2 and 3, through their connectionto the bracket 15 by the rods 13 and 141, are swung accordingly. Theseat-support 7 is slightly inclined but my improvement will operateequally as well if the seat-support was perfectly vertical.

I have shown my improvement as applied to a reversible plow asillustrated and described in my Patent No. 979,019 issued December 20,1910, but it is evident that it can be applied to any plow havingadjustable furrow-wheels.

-What I claim is- 1. In a sulky-plow, the combination with a frame, ofsupporting wheels including front and rear furrow wheels, and meanssubstantially central of the plow and movable upwardly and downwardlyand connected with the furrow-wheels, to adjust the latter.

2. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, and means substantially centralof the plow and movable upwardly and downwardly and connected with thefurrow-wheels to adjust the latter simultaneously.

3. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seat-support, and means on theseat-support and connected with the furrow-wheels and movable upwardlyand downwardly to adjust the furrow-wheels.

4. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seat support substantiallycentral of the plow, and means on the seat-support and connected withthe furrow-wheels and movable up wardly and downwardly to adjust thefurrow-wheels.

5. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seat-support, an upwardly anddownwardly movable bracket on the seat-support, and connections betweenthe furrow-wheels and the bracket to adjust the furrow-wheels with anupward or downward movement of the bracket. I

6. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seat support substantiallycentral of the plow, an upwardly and downwardlymovable bracket on theseat support, and means connecting the furrow-wheels and the bracket toadjust the furrowwheels with an upward or downward movement of thebracket.

7. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seats upport, an upwardly anddownwardly movable bracket on the seat-support, a connec tion betweenthe front furrow-wheel and the furrow side of the bracket, a connectionbetween the landside of the bracket and the rear furrow-wheel, and meansto raise or lower the bracket to adjust the furrowwheels.

8. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seat-support, an upwardly anddownwardly movable bracket on the seat-support, a connection betweeneach furrow'wheel and the bracket, and a lever to move the bracketupwardly and downwardly to adjust the furrow-wheels.

9. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-wheels, a seat-support and the tongue,and means on the v brace and connected to the bracket to move the latterto adjust the furrow-wheels.

11. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front'and rear furrow-wheels, a seat support, an upwardly anddownwardly movable bracket on the seat-support, connections between thefurrow-wheels and the bracket, and means forward of the seatsupport andconnected with the bracket to move the latter to adjust the furrow-'wheels.

12. In a sulky-plow, the combination with a frame, of supporting wheelsincluding front and rear furrow-whels, a seat-support, an upwardly anddownwardly movable bracket on the seat-support, means to connect thefurrow-wheelswith the bracket, a forward brace for the seat-support, anda lever on the brace to -move the bracket to adjust the furrow-wheels.

13. In asulky-plow, the combination with a frame, of' supporting wheelsincluding front and rear furrow-wheels, a seat support, an upwardly anddownwardly movable bracket on the seat-support, means to connect thefurrowwheels with the bracket, a brace for the seat-support, atoothed-segment on the brace, a lever engaging with the segment, an armon the bracket, and a link connecting the arm and the lever.

In testimony whereof I aflix my signature, in presence of two witnesses.
